Is there a way to return an RB Picture object with alpha channel (new in 2011r4) from a plugin? Currently, I'm using REALBuildPictureFromBuffer with the RBPixelType "kRBPixelBGRX32." I was kinda thinking that with these fancy new alpha-enabled Picture objects, we'd get a new pixel type of maybe "kRBPixelBGRA32," or "kRBPixelRGBA32" or something.
